DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT(S)

Aspects of the present invention relate to head-worn computing (“HWC”)systems. HWC involves, in some instances, a system that mimics theappearance of head-worn glasses or sunglasses. The glasses may be afully developed computing platform, such as including computer displayspresented in each of the lenses of the glasses to the eyes of the user.In embodiments, the lenses and displays may be configured to allow aperson wearing the glasses to see the environment through the lenseswhile also seeing, simultaneously, digital imagery, which forms anoverlaid image that is perceived by the person as a digitally augmentedimage of the environment, or augmented reality (“AR”).

HWC involves more than just placing a computing system on a person'shead. The system may need to be designed as a lightweight, compact andfully functional computer display, such as wherein the computer displayincludes a high resolution digital display that provides a high level ofemersion comprised of the displayed digital content and the see-throughview of the environmental surroundings. User interfaces and controlsystems suited to the HWC device may be required that are unlike thoseused for a more conventional computer such as a laptop. For the HWC andassociated systems to be most effective, the glasses may be equippedwith sensors to determine environmental conditions, geographic location,relative positioning to other points of interest, objects identified byimaging and movement by the user or other users in a connected group,and the like. The HWC may then change the mode of operation to match theconditions, location, positioning, movements, and the like, in a methodgenerally referred to as a contextually aware HWC. The glasses also mayneed to be connected, wirelessly or otherwise, to other systems eitherlocally or through a network. Controlling the glasses may be achievedthrough the use of an external device, automatically throughcontextually gathered information, through user gestures captured by theglasses sensors, and the like. Each technique may be further refineddepending on the software application being used in the glasses. Theglasses may further be used to control or coordinate with externaldevices that are associated with the glasses.

Referring to FIG. 1, an overview of the HWC system 100 is presented. Asshown, the HWC system 100 comprises a HWC 102, which in this instance isconfigured as glasses to be worn on the head with sensors such that theHWC 102 is aware of the objects and conditions in the environment 114.In this instance, the HWC 102 also receives and interprets controlinputs such as gestures and movements 116 of a body part of a user. TheHWC 102 may communicate with external user interfaces 104. The externaluser interfaces 104 may provide a physical user interface to takecontrol instructions from a user of the HWC 102 and the external userinterfaces 104 and the HWC 102 may communicate bi-directionally toaffect the user's command and provide feedback to the external device108. The HWC 102 may also communicate bi-directionally with externallycontrolled or coordinated local devices 108. For example, an externaluser interface 104 may be used in connection with the HWC 102 to controlan externally controlled or coordinated local device 108. The externallycontrolled or coordinated local device 108 may provide feedback to theHWC 102 and a customized GUI may be presented in the HWC 102 based onthe type of device or specifically identified device 108. The HWC 102may also interact with remote devices and information sources 112through a network connection 110. Again, the external user interface 104may be used in connection with the HWC 102 to control or otherwiseinteract with any of the remote devices 108 and information sources 112in a similar way as when the external user interfaces 104 are used tocontrol or otherwise interact with the externally controlled orcoordinated local devices 108. Similarly, HWC 102 may interpret gestures116 (e.g. captured from forward, downward, upward, rearward facingsensors such as camera(s), range finders, IR sensors, etc.) orenvironmental conditions sensed in the environment 114 to control eitherlocal or remote devices 108 or 112.

We will now describe each of the main elements depicted on FIG. 1 inmore detail; however, these descriptions are intended to provide generalguidance and should not be construed as limiting. Additional descriptionof each element may also be further described herein.

The HWC 102 is a computing platform intended to be worn on a person'shead. The HWC 102 may take many different forms to fit many differentfunctional requirements. In some situations, the HWC 102 will bedesigned in the form of conventional glasses. The glasses may or may nothave active computer graphics displays. In situations where the HWC 102has integrated computer displays the displays may be configured assee-through displays such that the digital imagery can be overlaid withrespect to the user's view of the environment 114. There are a number ofsee-through optical designs that may be used, including ones that have areflective display (e.g. LCoS, DLP), emissive displays (e.g. OLED, LED),hologram, TIR waveguides, and the like. In embodiments, lighting systemsused in connection with the display optics may be solid state lightingsystems, such as LED, OLED, quantum dot, quantum dot LED, etc. Inaddition, the optical configuration may be monocular or binocular. Itmay also include vision corrective optical components. In embodiments,the optics may be packaged as contact lenses. In other embodiments, theHWC 102 may be in the form of a helmet with a see-through shield,sunglasses, safety glasses, goggles, a mask, fire helmet withsee-through shield, police helmet with see through shield, militaryhelmet with see-through shield, utility form customized to a certainwork task (e.g. inventory control, logistics, repair, maintenance,etc.), and the like.

The HWC 102 may also have a number of integrated computing facilities,such as an integrated processor, integrated power management,communication structures (e.g. cell net, WiFi, Bluetooth, local areaconnections, mesh connections, remote connections (e.g. client server,etc.)), and the like. The HWC 102 may also have a number of positionalawareness sensors, such as GPS, electronic compass, altimeter, tiltsensor, IMU, and the like. It may also have other sensors such as acamera, rangefinder, hyper-spectral camera, Geiger counter, microphone,spectral illumination detector, temperature sensor, chemical sensor,biologic sensor, moisture sensor, ultrasonic sensor, and the like.

The HWC 102 may also have integrated control technologies. Theintegrated control technologies may be contextual based control, passivecontrol, active control, user control, and the like. For example, theHWC 102 may have an integrated sensor (e.g. camera) that captures userhand or body gestures 116 such that the integrated processing system caninterpret the gestures and generate control commands for the HWC 102. Inanother example, the HWC 102 may have sensors that detect movement (e.g.a nod, head shake, and the like) including accelerometers, gyros andother inertial measurements, where the integrated processor mayinterpret the movement and generate a control command in response. TheHWC 102 may also automatically control itself based on measured orperceived environmental conditions. For example, if it is bright in theenvironment the HWC 102 may increase the brightness or contrast of thedisplayed image. In embodiments, the integrated control technologies maybe mounted on the HWC 102 such that a user can interact with itdirectly. For example, the HWC 102 may have a button(s), touchcapacitive interface, and the like.

As described herein, the HWC 102 may be in communication with externaluser interfaces 104. The external user interfaces may come in manydifferent forms. For example, a cell phone screen may be adapted to takeuser input for control of an aspect of the HWC 102. The external userinterface may be a dedicated UI, such as a keyboard, touch surface,button(s), joy stick, and the like. In embodiments, the externalcontroller may be integrated into another device such as a ring, watch,bike, car, and the like. In each case, the external user interface 104may include sensors (e.g. IMU, accelerometers, compass, altimeter, andthe like) to provide additional input for controlling the HWD 104.

As described herein, the HWC 102 may control or coordinate with otherlocal devices 108. The external devices 108 may be an audio device,visual device, vehicle, cell phone, computer, and the like. Forinstance, the local external device 108 may be another HWC 102, whereinformation may then be exchanged between the separate HWCs 108.

Similar to the way the HWC 102 may control or coordinate with localdevices 106, the HWC 102 may control or coordinate with remote devices112, such as the HWC 102 communicating with the remote devices 112through a network 110. Again, the form of the remote device 112 may havemany forms. Included in these forms is another HWC 102. For example,each HWC 102 may communicate its GPS position such that all the HWCs 102know where all of HWC 102 are located.

FIG. 2 illustrates a HWC 102 with an optical system that includes anupper optical module 202 and a lower optical module 204. While the upperand lower optical modules 202 and 204 will generally be described asseparate modules, it should be understood that this is illustrative onlyand the present invention includes other physical configurations, suchas that when the two modules are combined into a single module or wherethe elements making up the two modules are configured into more than twomodules. In embodiments, the upper module 202 includes a computercontrolled display (e.g. LCoS, DLP, OLED, etc.) and image light deliveryoptics. In embodiments, the lower module includes eye delivery opticsthat are configured to receive the upper module's image light anddeliver the image light to the eye of a wearer of the HWC. In FIG. 2, itshould be noted that while the upper and lower optical modules 202 and204 are illustrated in one side of the HWC such that image light can bedelivered to one eye of the wearer, that it is envisioned by the presentinvention that embodiments will contain two image light deliverysystems, one for each eye. It should also be noted that while manyembodiments refer to the optical modules as “upper” and “lower” itshould be understood that this convention is being used to make iteasier for the reader and that the modules are not necessarily locatedin an upper-lower relationship. For example, the image generation modulemay be located above the eye delivery optics, below the eye deliveryoptics, on a side of the eye delivery optics, or otherwise positioned tosatisfy the needs of the situation and/or the HWC 102 mechanical andoptical requirements.

An aspect of the present invention relates to the mechanical andelectrical construction of a side arm of a head worn computer. Ingeneral, when a head worn computer takes the form of glasses,sun-glasses, certain goggles, or other such forms, two side arms areincluded for mounting and securing the had worn computer on the ears ofa person wearing the head worn computer. In embodiments, the side armsmay also contain electronics, batteries, wires, antennas, computerprocessors, computer boards, etc. In embodiments, the side arm mayinclude two or more sub-assemblies. For example, as will be discussed inmore detail below, the side arm may include a temple section and an earhorn section.

The two sections may, for example, be mechanically arranged to allow anear horn section to move such that both side arms can fold into a closedposition.

FIGS. 3A, 3B, and 3C illustrate three separate views 102A, 102B and 102Cof a head worn computer 102 according to the principles of the presentinvention. Turning to the head worn computer illustrated as 102A in FIG.3A, one side arm of the HWC 102 is folded into its closed position. Theear horn section 308 of the side arm is rotated relative to its templesection 304 to create space relative to the other side arm 310 so whenthe other side arm is moved into its closed position it can fully close.In a situation where the ear horn did not rotate to create the space(not illustrated) the ear horn would physically interfere with the otherside arm 310, when the side arm was in the closed position, and preventthe other side arm 310 from fully closing. The HWC 102B view in FIG. 3Billustrates the HWC 102B with both side arms folded into a fully closedposition. Note that the ear horn 308 is in the rotated position withrespect to its temple section 304 such that the other arm 310 closedwithout interfering with the ear horn 308. The HWC 102C view in FIG. 3Calso illustrates both arms in closed positions with the ear horn 308rotated to create the space for the other arm 310 to fully close. FIG.3C also illustrates a portion of the HWC 102 where electronics may behoused in a top mount 312. The top mount may contain electronics,sensors, optics, processors, memory, radios, antennas, etc.

FIG. 4A and FIG. 4B illustrate a side arm configuration in accordancewith the principles of the present invention. In this embodiment, theside arm includes two sub-assemblies: the temple section 304 and the earhorn 308. FIG. 4A and FIG. 4B illustrate two views of the side armassembly, one from an outer perspective in FIG. 4A and one from asectioned perspective in FIG. 4B. The ear horn includes a pin 402 thatis designed to fit into a hole 404 and to be secured by connector 408.The connector 408 is rotatable and in one position locks the pin 402 inplace and in another position unsecures the pin 402 such that the earhorn 308 can be removed and re-attached to the temple section 304. Thisallows the detachment and re-attachment of the ear horn 308 from thetemple section 304. This also allows for the sale of different ear horns308 for replacement, of which a variety of colors and patterns may beoffered. In embodiments, the temple section 304 may include a batterycompartment 410 and other electronics, wires, sensors, processors, etc.

FIG. 5A, FIG. 5B, FIG. 5C, FIG. 5D, FIG. 5E, and FIG. 5F illustrateseveral views of a HWC side arm with temple 304 and ear horn 308sections. The views include outer perspectives and cross sections aswell as various states of the security of the ear horn 308 with thetemple section 304. FIGS. 5C and 5D illustrates the ear horn 308 and thetemple section 304 in a secure un-rotated position. The same pin 402 andconnector 408 system described in connection with FIG. 4A and FIG. 4B isillustrated in the cross sections of FIG. 5B, FIG. 5D, and FIG. 5F. Inthe secured un-rotated position the pin is pulled internally within thetemple section firmly such that it stays in place. FIG. 5C and FIG. 5Dillustrates a state where the ear horn 308 is separated from the templesection 304. This state is achieved when pressure is used to pull on theear horn 308. In embodiments, the pressure is exerted by a user pullingon the ear horn 308, which compresses a spring 510B that is mechanicallyassociated with the pin 402 in the ear horn 308. The mechanism uses thespring to maintain pressure on the pin 402 to maintain connection withthe connector 408 when the connector 408 is in a position to lock thepin 402 in position. FIGS. 5E and 5F illustrate a state where, after theear horn 308 has been pulled into the state described in connection withFIGS. 5C and 5D, the ear horn 308 is rotated about the pin 402. Thisputs the ear horn 308 in a rotated position as described herein suchthat the first arm, with this rotated ear horn 308, does not interferewith the closure of the other arm 310 when the two arms are folded intothe closed position.

An aspect of the present invention relates to an adjustable nose bridge.An adjustable nose bridge may be important with head worn computers,especially those with computer displays, to ensure comfort and alignmentof the displays and/or other portions of the head worn computer. FIG. 6illustrates a HWC 102 with an adjustable nose bridge 602. The nosebridge is adjustable through a mechanism in the HWC 102. In embodiments,the mechanism includes a fixed notched attachment 604, a movable pin 608adapted to fit into the notches of the notched attachment 604, and aselection device 610 that is attached to the movable pin 608. Themovable pin 608 and nose bridge 602 are connected such that the as themovable pin 608 shifts in position the nose bridge 602 moves in positionas well. The selection device 610 causes the movable pin 608 to engageand disengage with the fixed notched attachment 604 when presses andallowed to retract. As illustrated in FIG. 6, the selection device 610is not in a pressed position so the movable pin 608 is engaged with thenotched attachment 604 such that the nose bridge is securely attached ina stable position. FIG. 7 illustrates a scenario where the selectiondevice is pressed, or activated, such that the movable pin 608 is nolonger engaged with the fixed notched attachment 604. This allows thenose bridge 602 to move up and down with respect to the rest of the HWC102. Once the movable pin 608 aligns with a notch of the notchedattachment 604, the two parts may engage to re-secure the nose bridge inthe HWC 102.

In embodiments, a side arm of the HWC 102 may include an audio jack (notshown) and the audio jack may be magnetically attachable to the sidearm. For example, the temple section 304 or ear horn section 308 mayhave a magnetically attachable audio jack with audio signal wiresassociated with an audio system in the HWC 102. The magnetic attachmentmay include one or more magnets on one end (e.g. on the head phone endor the side arm end) and magnetically conductive material on the otherend. In other embodiments, both ends of the attachment may have magnets,of opposite polarization, to create a stronger magnetic bond for theheadphone). In embodiments, the audio signal wires or magneticconnection may include a sensor circuit to detect when the headphone isdetached from the HWC 102. This may be useful in situations where thewearer is wearing the headphones during a period when there is notconstant audio processing (e.g. listening for people to talk withperiods of silence). In embodiments, the other side's headphone may playa tone, sound, signal, etc. in the event a headphone is detached. Inembodiments, an indication of the detachment may be displayed in thecomputer display.

In embodiments, the HWC 102 may have a vibration system that vibrates toalert the wearer of certain sensed conditions. In embodiments, thevibration system (e.g. an actuator that moves quickly to cause vibrationin the HWC 102) may be mounted in a side arm (e.g. the temple section304, or ear horn 308), in the top mount 312, etc. In embodiments, thevibration system may be capable of causing different vibration modesthat may be indicative of different conditions. For example, thevibration system may include a multi-mode vibration system,piezo-electric vibration system, variable motor, etc, that can beregulated through computer input and a processor in the HWC 102 may sendcontrol signals to the vibration system to generate an appropriatevibration mode. In embodiments, the HWC 102 may be associated with otherdevices (e.g. through Bluetooth, WiFi, etc.) and the vibratory controlsignals may be associated with sensors associated with the other device.For example, the HWC 102 may be connected to a car through Bluetoothsuch that sensor(s) in the car can cause activation of a vibration modefor the vibration system. The car, for example, may determine that arisk of accident is present (e.g. risk of the driver falling asleep, cargoing out of its lane, a car in front of the wearer is stopped orslowing, radar in the car indicates a risk, etc.) and the car's systemmay then send a command, via the Bluetooth connection, to the HWC 102 tocause a vibratory tone to be initiated in the HWC 102.

Although embodiments of HWC have been described in language specific tofeatures, systems, computer processes and/or methods, the appendedclaims are not necessarily limited to the specific features, systems,computer processes and/or methods described. Rather, the specificfeatures, systems, computer processes and/or and methods are disclosedas non-limited example implementations of HWC.
